Was external power connected at the time of a reboot? Only then will
firmware be updated. If not, it's a bug, and I'll need to work with you
to determine the cause. Let me know if the external power was connected
before a reboot?

No, I don't think so.

It should also happen after an olpc-update, is that what you did? It's
not clear from your mail. How did you reach os852; using fs-update,
using four game key press, or using olpc-update?

No, Q3A48 is the firmware version embedded in os852. You need Q3A50 on
a NANDblaster sender though.

The sender picks the channel with the least activity. The receiver
checks all channels for a sender.

Yes, forcing the channel may increase the chances of success, but doing
it without knowledge of the radio conditions may decrease the chances of

This may change.

There are instructions for setting up the receiver ... start them with
the four game keys held down, says the page. Then it says ... if this
does not work, you may need to manually update the firmware first. This
should not be required for laptops shipped recently.
If you've been using prototype laptops then you may need to upgrade the
firmware version first. What firmware version are they? You mentioned
Q3A36 above. This is far too old. The Wiki page says you should use
Q3A45 or later if the laptops do not start receiving.
The instructions do not describe how to upgrade the firmware first,
because in most cases that will not be required, and besides the time
cost of checking the firmware version is higher than the time cost of
just trying to receive the broadcast.
The procedure is optimised for mass deployment, not mass upgrade.
